To all 'whom t may concern:

Be it known that I, FREDERICK GROVER, a subject of the King of GreatBritain, residing at Leeds, in the county of York, England, haveinvented certain new and useful Improvements in lVrapping-Machines, ofwhich the following isV a specification.A y

This invention relates to machines for automatically wrappingrectangular tablets, -such as chocolate cakes, in one or more 1nnerwrappers and an outside binder or label.

The present invention has particular reference to a previously proposed'wrapping machine designed for folding a label around an already wrappedtablet. In this reviously described machine, a pile of abelsis containedin a vertical open-topped box having corner pieces against which the toplabel 1s normally held by means of a carrying plunger pressed up by acounterbalance weight arrangement and having a mechanically operatedbrake to hold the plunger at certain times in a lower position when s oplaced, and a step-bystep rotating horizontal disk is providedhaving aseries of through apertures formed with depend ing' side lugs which arecaused to conta with a-gum roller prior to each aperture being broughtto rest above the label box, provided mechanism being employed to causethe disk to then descend in the direction of its axis to bring thegummed lugs on to the top of the pile of labels and depress the same,the brake operating to hold the label plunger in its e depressedposition, while the disk is then vpermitted'to rise to lift the toplabel from .the pile and flick its corners past the corners'of the labelbox, when the succeeding intermittent partial rotation of the diskcarries the label to a position to receive a tablet which issubsequently delivered to folding mechanism.

The present object is to construct the labeling machine above referredto in such a 'manner as to cause the step-by-step rotating disk to takeup one or more inner wrappers (hereinafter referred to as a wrapper)prior to being caused to take up a label from the label box, thearrangement being such that the wrapper and the label t0- gether arecarried by the intermittently moved disk to a position to receive thetablet ready for the subsequent wrapper-folding v operation whereby 'theinclosing ofthe tablet in one or more wrappers can be performedsimultaneously with the folding of a label around the said tablet. Tothis end, a stepby-step rotating disk is employed having a Series ofthrough apertures formed with depending side lugs working in conjunctionwith a gum roller and a label box as before; and on the underside of thesaid disk at the ends of each through aperture arefixedv depending pins,say two .at each end, arranged outside or beyond the depending lugs soas not to interfere in any way with the label which'is to be carried bythe latter. At the opposite side of the disk to that at which the tabletis fed or at` any other suitable position anddirectly beneath one of theapertures of the disk (assuming the latter to be stationary), isprovided a fixedtable on to which an inner wrapper is fed say from areel by feed rollers working in conjunction with a cutting device so asto deliver wrappers of a predetermined length.

As the step-by-step rotating disk is intermittently moved around, thedepending lugs rst take Aup the adhesive from the gum roller, when onthe said disk coming over the wrapper its depression at this pointcauses. the provided pins on its underside to pierce the said wrapper,pick it up and carry it a step forward to a position above `thelabelbox, Where the disk by being again depressed causesthe gummed lugs topick up the uppermost label from the label box, while the 'effect of thesubsequent forward step or steps of the said disk is to carry the innerwrapper and also the outside label t0- gether forward to thev positionto receive the tablet.

The inner wrapper carried by the pins of the step-by-step rotating diskis situated above the label'carried by the gummed lugs 0F LEEDS,ENGLAND, ASSIGNOR T0 THE FORGROVE MAQHINERY COMPANY LIMITED, 0F LEEDS,IEIIGrllaAlH).A

sov

of the said disk, the width of the wrapper being such as not to extendup to the gunimed portions of the label while the ends ofthe saidwrapper extend loutward beyond the ends of the saidA label so as tosubsequently constitute the end folds. On the wrapper and the labelbeing together brought by the step-by-step rotating disk to theposition-to receive the tablet, the latter is fed into position by anyknown convenient means. when the tablet and its Wrapper and label aredelivered to folding 1 mechanism of any known or convenient con.-struction capable of folding over-the ends and sides of the wrapper andof simultaneously folding over the sides of the label; the gum havingthe effect of'securing the inner wrapper and the outside label inposition around the tablet.

The invention will now be described with reference to the example ofconstruction shown in the accompanying drawings, in

which corresponding numerals indicate like' parts in all the figures;wherein:-

, Figures 1 and 2 are respectively a sectional side elevation and a planof theflabel pile of labels 3 carried upon the verticalA plunger 4, and5 is the step-by-step rotating disk mounted on the vertical shaft 6 andhaving through apertures 7 formed with depending side lugs 8 adapted tomake contact with the gumming-roller 9 of the gum trough 10 mounted onthe bed-plate 2, while 11 is the slide by way of which the tablets afterbeing wrapped are delivered; all the `parts enumerated being of knownconst-ruction.

According to the present invention depending pins 12 are iixed on theunderside of the disk 5, at the ends of each of the through apertures 7,which depending pins 12 are situated outside or beyond the dependinglugs 8 so as not to interferein any way with the label which is to becarried by the latter, while 4immediately beneath the disk 5 and at theside opposite to that of the tablet delivery-slide 11 is provided afixed table 13 on to which by-means of feed rollers 14 a wrapper 15 isfed from a reel, (not shown), the wrapper beingr cut off to apredetermined length by a cutting device 16 so vas to leave the saidwrapper 15 resting on the table 13 directly beneath one of the apertures7 of the disk 5, and holes 17 are formed in the table 13 for admittingthe points of the pins 12 011 the disk 5 being depressed.

In the example of construction shown in the drawings, each forwardstepof the disk -5 is made equal to a sixth portion of a single revolution.The forward movement therefore of the, disk 5 in the direction of thearrow (see Fig. 2) from A to B causes the 'depending side lugs 8 torecei-ve .adhe' sive from the gum roller 9. while the next step forwardfrom B to C brings oneV of the apertures 7 of the disk 5 over thewrapper 15. when the depression of the disk 5 Aat this point causes theprovided pins 12 on its underside to pierce the said wrapper 15 and pickit up, and the next step forward of the disk 5 from C t-o D brings thesame aperture 7 over the label box 1, when the depression of the disk 5at this point causes the gummed lugs 8 to pick up the uppermost label 3from the label box 1, while the subsequent steps forward of the disk 5from D to E and E to F bring the carried Wrapper 15 and label 3 to theposition to receive the tablet. In this way, the wrapper 15 carried bythe pins 12 of the step-by-step` rotating disk 5 is situated above thelabel 3 carried by the gummed lugs 8 of the said disk 5 asshown at Fig.3; and in these relative positions the said Wrapper 15 and label 3 arebrought by the disk 5 to the position F (Fig. 2) where they receive thetablet, around which they are subsequently l folded by any known orconvenient folding mechanism as beforestated.
